Schwanoma of tonsil

Tonsil fibromatosis.

Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...

Primary adenomyoepithelioma of tonsil

We present a case of adenomyoepithlioma (AME) arising from the tonsil. AME is an uncommon tumor that typically arises in breast, but rarely found in salivary glands, lung, and skin. Its biological features have not been thoroughly characterized. Here we describe a primary AME originating from the tonsil. The pathologic changes were characterized by hypercellularity, the dominance of both epithe...

Schwannoma of the tonsil.

Between 25 and 48% of schwannomas have been reported to occur in the head and neck region; the acoustic nerve is involved in most cases. Schwannomas arising in the tonsil are extremely uncommon. We report a case of tonsillar schwannoma in a 23-year-old woman. We also review the literature on this rare entity.

The Technique of Tonsil Enucleation

Inflammatory pseudotumor of the tonsil.

Inflammatory pseudotumor is an unusual benign but potentially invasive lesion. In the head and neck area, it mainly involves the orbit and paranasal sinuses. We present a case in tonsil and neck. After tonsillectomy and steroid therapy, there has been no recurrence.
